The UK’s first cordless telephone exchange goes into service in Margate. Desks with discrete buttons and keys switch the queued calls. About 30 operators are employed during the day at the Thanet Exchange. During the holiday season, the staff is increased to between 40 and 50 at nights to deal with cheap rate long distance calls. On the average. Thanet Exchange operators handle about 3,000 calls a day and about 1,400 to 1,500 in the evenings. During the summer, however. the overall daily figure leaps to about 10,000.
